Gamma-ray telescope

...However, in the case of high-energy gamma rays, the opening angle of the paired electrons produced by electron pair production is narrow, and the direction of their arrival can be determined by measuring their direction of travel using a spark chamber or a nuclear emulsion plate. By combining these techniques according to the purpose of observation and the level of precision, so-called gamma ray telescopes have been built to measure the energy and direction of gamma rays. As of the end of 1997, the location and mechanism of gamma ray bursts remain a mystery. ...

Japanese:

…しかしながら,エネルギーの高いγ線の場合,電子対生成でできる対電子の開角が狭く,その進行方向をスパークチェンバーや原子核乾板などによって測定して到来方向を決めることができる。 このような手法を,観測目的や精度に応じて組み合わせて,γ線のエネルギーや到来方向を測定するいわゆるγ線望遠鏡がつくられている。 1997年末現在,γ線バーストの発生場所,発生機構は依然として謎につつまれている。…
